DDR2 Memory
The Pico E‐14 comes equipped with 256 MB of PC‐266 DDR2 memory. There are four 256Mb chips
each with 16 bit data paths that are grouped into two 32 bit banks. From 0°C to +95°C, the ram can run
at 266 MHz. For operation at temperatures below 0°C, special firmware with reduced ram timings is
required. The temperature compensated self‐refresh mode must be disabled below ‐20°C.
